==Commerce and industry==
The Texas [[Quarry]], near of the intersection of I-83 and Warren Road, dating back to the 19th century, produces [[limestone]] and [[marble]], including the marble used in the first phase of construction (1848–54) of the [[Washington Monument]], the whiter portion towards the bottom half of the monument. During the second phase of construction (1880–84) the monument had to be finished using a slightly different-colored stone, most of which came from the [[Beaver Dam Quarry]] (now Beaverdam Pond) near the intersection of Beaver Dam Road and McCormick Road.<ref>{{google maps|url=https://maps.google.com/?ll=39.469065,-76.65247&spn=0.033924,0.054846&t=h&z=14&vpsrc=6 |title=Marble quarries near Cockeysville, MD |access-date=January 31, 2013}}</ref><ref>{{cite web |url=https://archive.org/details/TheHistoryOfTheMarbleQuarriesInBaltimoreCountyMaryland |title=The history of the marble quarries in Baltimore County, Maryland |author=William D.

Blocks of local marble were also used in 1836 as rail supports in the [[track bed]] for the Padonia Road section of the [[Baltimore and Susquehanna Railroad]] (which later became part of the [[Northern Central Railway]]); the use of marble instead of wood was an experiment that was soon after abandoned.<ref>[http://www.hmdb.org/marker.asp?marker=4340 Baltimore and Susquehanna Railroad Marble Track Bed] from the Historical Marker Database</ref>
